" neuroplasticity’, a term which takes into account the fact that the brain evolves continuously in relation to our experience, and that a particular training, such as learning a musical instrument or a sport, can bring about a profound change. Mindfulness, altruism and other basic human qualities can be cultivated in the same way. In general, if we engage repeatedly in a new activity or train in a new skill, modifications in the neuronal system of the brain can be observed within a month. What is essential, therefore, is to meditate regularly. "
